Stosur stuns Williams to win U.S. Open title

Australia's Sam Stosur upset American Serena Williams 6-2 6-3 on Sunday to win an ill-tempered U.S. Open women's final.

Stosur played the match of her life to defeat the most formidable player of her generation and capture her first grand slam title, spoiling American hopes of a home-bred champion on the 10th anniversary of the Sept. 11 attacks.

Williams, bidding for a fourth U.S. Open crown, failed to reproduce her best after sailing to the final without dropping a set and let her frustrations boil over.
